And what about that surprise at 3:51? More of that 2018 jazzy major-9 business followed by a frigging VII chord (E♭), which I kind of hear as an augmented 6th chord. Yes, I said “augmented 6th chord” in an article about Top 40 music in 2018 — pick your face up off the floor.
Chorus impact accentuators, often abbreviated to “CIAs,” is a term that’s still fairly new in this category — whether people know about it at all yet — but it keeps popping up more and more nowadays. Simply put, chorus impact accentuators are any element in a production that makes the chorus more impactful and powerful. That can be a reversed crash cymbal sample that flares up and preps our ears for a drop, or even a half a measure of complete silence leading up to the chorus, making its arrival all the more epic.
